I think, therefore I am.

There are no bad mistakes in maths, only discoveries.

A book a day keeps the stupidity away.

If you fail, next time fail better.

It doesn’t matter where you start, it matters how you end

Don’t be afraid to work hard and find out how good you can really be.

The temptation to quit will be the greatest when you are about to succeed

Hope might be a good breakfast, but it makes a very poor dinner

Hard work - a two way street where you get exactly what you put in.

Don't be afraid to take an unfamiliar path.  Sometimes they're the ones that lead you to the best places.

Practice makes comfort. Expand your experiences regularly so every stretch won't feel like your first.

If you can understand just one thing thoroughly, then you will understand everything.

Pure mathematics is in its way, the poetry of logical ideas.

I fear not the man who has practiced 10,000 kicks once, but I fear the man who has practiced one kick 10,000 times.

Don't fear failure, fear being in the same exact same place next year as you are now.
